Drinking and diving

Here are a few reason why you should avoid drinking alcohol and scuba dive


1. You're risking Decompression sickness

You get more nitrogen in your system: Through an increase in peripheral circulation

Because alcohol increase blood flow, you could be absorbing 

You get rid of it slower: Through dehydration
How funny that while being in water, dehydration is probably the number one risk factor for DCS and is already a problem for divers who did not consume alcohol: the pressure, the cold and the tight suit make you want to pee all the time! -> you’re losing liquid= dehydration
Alcohol has diuretic properties (makes you urinate even more) 
Haven’t you wondered why pub’s toilets are always packed?
Hence you pee twice more and get dehydrated twice more.
Your blood is thicker, its circulation slower and the elimination of nitrogen bubbles altered.
That’s also why you should not drink too much alcohol even after dives as you are in the process of getting the nitrogen out of your system.

What should you do to stay hydrated?

When you go diving: before and after a dive, especially when you are on a liveaboard trip and do several days of diving, Drink plenty of water before feeling thirsty.
Attention: Drinking coffee, tea or sodas (or beer!) are not as good as drinking water.
It has been said that ideally we should drink one liter of water after every dive.
Eating yogourts, fruits and vegtables rich in water helps you fight dehydration as well as food rich in potassium such as bananas.
It is recommended to stop drinking alcohol (moderately) at least 8 hours before your next dive.
Avoid doing sport or sun bathing after the dives as they also make you more dehydrated.

2. you get cold faster

For a diver, body heat loss is of significant concern. This is because in water, the body loses heat 25 times faster than in air. Alcohol is known to be a peripheral vasodilator; it makes blood vessels to widen more than usual.  As blood flows into the dilated vessels, it withdraws heat from the core to surface of the body; although this may bring about a flush of warm feeling, it is short-lived and predisposes the body to hypothermia. Research conducted recently out of Canada indicate that nitrogen narcosis is responsible for delay in shiver response, an important indicator of a considerable heat loss from the body, alcohol is also known to depress the response; complicating the heat loss problem further.

3. Drunken effect of alcohol and depth combine: you're losing it

The danger imposed here is that, a diver may be unable to deal with an emergency, something which may land the diver into an accident.
Have you heard of the “martini’s law”? It states that every 15 meters a diver descends is equivalent in effect to drinking a glass of Martini. And of course both alcohol and nitrogen narcosis combine.
